TPS40130DBTR is a DC-DC switching controller IC. It can be used to control an external high-side smart switch to yield an ideal, regulated buck converter. It is part of the Texas Instruments\' power management integrated circuit (PMIC) family and more specifically a DC-DC Voltage Regulator.

The TPS40130DBTR controller is a high-performance, high-efficiency DC-DC Buck Mode voltage regulator controller. The IC has several features to ensure good line and load regulations that include a built-in feedback compensation network, internal current limit, and low voltage detection. It has an adjustable soft-start feature and pulse-skipping mode to meet the applications of ultra-low standby-power consumption. It also has an open-drain PGOOD output and Over-Current Protection circuitry (OCP) for easy system monitoring and protection.

The TPS40130DBTRs enhanced control loop optimizes the transient response for stability and accuracy regardless of frequency and output voltage. With an integrated current-sense Amplifier, the regulator designs are simple and efficient. In its Shutdown Control section, this DC-DC switching controller supports various external shutdown control circuits such as external push button and digital interface through its low voltage shutdown (LVR) and high voltage shutdown (HVR) input pins.

The TPS40130DBTR is available in the 4-lead Thermally Enhanced Plastic SOP package, provided a wide range, automotive temperature grade and computer grade.

TPS40130DBTR applications fields include Computer, Computer Peripheral, Consumer Electronics, Industrial, Automotive, as well as applications with ultra low standby-power requirements.

The TPS40130DBTR working principle is to allow the controller to output a single-ended PWM signal with a controllable dead-time for controlling a MOSFET switch. Compared to the classic non-controlled switch, the switch enables allows the buck regulator to operate in pulse-skipping or low-noise, fixed frequency mode with less ringing and switching losses.

The device also has a restart function which uses the voltage of the VCC pin to detect a restart. When the restart threshold voltage VOR is reached, the device triggers off a restart and the device restarts for VCC rising above VOR.

The TPS40130DBTR also has a digital reset input (RST) pin that is used to reset the IC logic, the soft-start function, and the fault flags in the event of an over-current or a switch over-temperature fault detection.

The DC-DC switching controller IC ensures a precise and fast current limit thanks to the sense amplifier built-in. In case of overload, the VCC will drop and the OCP circuitry will detect it to protect the controller from overloading.

The TPS40130DBTR switching controller can operate in pulse-skipping mode and operate at a fixed frequency. The controller generate output voltage regulation in the range of 0.6V to 5V with excellent line and load regulation. The TPS40130DBTR also allows users to optimize the efficiency of their application continually as the input voltage, output voltage and output current are changed.

The TPS40130DBTR utilizes an internal voltage reference along with a single resistor to set an accurate feedback voltage, which allows high levels of accuracy. The parts also have an adjustable soft-start feature and an adjustable dead time feature to minimize output voltage overshoot. The overshoot can also be minimized by adding external capacitive or inductively coupled elements on the output and input of the regulation network.

The TPS40130DBTR DC-DC switching controller has several features to ensure good line and load regulations. It has an adjustable soft-start feature and pulse-skipping mode to meet the applications of ultra-low standby-power consumption. It also has an open-drain PGOOD output and Over-Current Protection circuitry (OCP) for easy system monitoring and protection. With these features, the TPS40130DBTR DC-DC switching controller is ideal for applications that require fast current limit, precise and accurate voltage control, and excellent line and load regulation.
